To all whom it may concern:

Be it known that we, FRED L. Arms and Flinn L. MACKENZIE, citizens ofthe United States, residing at Everett, in the county of Middleseir andState of Massachusetts, and Beverly, in the county of Essex and State ofli lassachusetts, respectively, have invented certain Improvements inMechanism for Use in Attaching Shank-Pieces to Shoes, of which thefollowing description, in connection with the accompanying drawings,isja specification, like reference characters on the drawings indicatinglike parts in the several figures. i

This invention relates to mechanism for use in operating on shoes towhich shank pieces are attached and is particularly designed forapplication to a fastening inserting machine adapted to tack the shankpieces to the shoes. y

in the manufacture of certain kinds of shoes, it is customary to attachto the shank portion of the insole of a shoe, prior to the laying on ofthe outsole, a shank piece calculated to strengthen the shank of theshoe and to improve the appearance of the shoe.

The shank piece is commonly reinforced by a metal strip applied to theunder side of the shank piece and extending lengthwise of the shankpiece along substantially its median line and, in the finer grades ofshoes, is molded from rubber or composition and is relatively stiff andinflexible so as to retain its shape under the pressure exerted by theoutsole laying machine. The shank piece facilitates the production ofthe desired ex terior contour and appearance of the tread surface of thehoe by reason of the molding of the outsole by the sole laying machineover the convexly curved outer surface of the shank piece. To the endthat the shoe may be durably constructed and symmetrically formed, it isessential that the plane surface of the shank piece at the forward endof the shank piece be accurately alined with the surface of the insoleforwardly of the shank piece as otherwise a space will be left in thefinished shoe either between the outsole and a the surface of the shankpiece or between the outsole and the insole adjacent to the shank piece,depending upon whether the plane surface of the shank piece is disposedinwardly or outwardly of the plane of the surface of the insole". Ineither case,=it wiil be seen that the outsole will not present thesmooth and even appearance which is very desirable in high grade shoesand that the wearing qualities of the shoe will be impaired by reason ofthe outsole not being properlysustained at all points.

In the manufacture of shoes in which shank pieces'of the kind abovedescribed are used, the outsole is molded to substantially the shapewhich it will have in the finished shoe previous to its application tothe shoe, there being formed in the outsole in the molding operation, awell-defined angle marking the break line between the shank portion andthe forepart of the outsole. Before the outsole is laid on the shoe, thesurface of the insole and shank piece and the inner surface of theoutsole are coated with cement which retains the outsole in positionuntil the permanent attachment of the outsole to the shoe When theoutsole is applied to the shoe the break line of the outs'ole shouldcoincide with the line of intact ing of the outer surface of the body ofthe shank piece with the plane surface at the forward end of the shankpiece hereinafter for convenience of description termed the break lineof the shank piece, but by reason of the break line of the shank piecebeing concealed by the outsole as it is laid on the shoe and inasmuch asthe cement prevents movement of the outsole relatively to the insole andshank piece after it is placed thereon, it is difficult for the operatorto locate the outsole exactly. with the result thata large proportion ofthe outsoles are not properly positioned. It is apparent that if theoutsole is not applied to the insole and attached shank piece in suchmanner that the break line of the outsole coincide with the break lineof the shank piece, the pressure exerted by the sole laying machine onthe outsole will form a crease in the outsole at the point where it liesover the break line of the shank piece greatly injuring the appearanceof the shoe.

In the present shop practice, the operator applies the shank piece tothe shank portion of the insole and presents the work to the throatpiece of a tacking machine, inserting a tack through the rear portion ofthe shank piece and into the insole at one side of the metal strip ofthe shank piece and then shifts the shoe relatively to the throat pieceand inserts a tack through the shank piece at the other side of themetal strip. In doing this work, the operator relies upon his eyes todetermine the proper position of the shank piece with the result thatthe shank pieces are very frequently attached to the shoes in such wisethat the surface of the shank piece projects too far outwardly or liestoo far inwardly from the surface of the insole with consequent lack ofsupport to a portion of the outsole when it is applied to the insole.The irregular location of the shank pieces adds to the difficulty ofproperly matching the break line of the outsole with the break line ofthe shank piece. Moreover, if the shank piece has not been properlyapplied to' the insole, the matching of the outsole with the shank pieceso that the break line of the'outsole coincides with the break line ofthe shank piece causes the outsole to be improperly located relativelyto the body of the shoe.

An object of this invention is to provide means whereby the defectsarising from present methods of applying the shank pieces may beobviated and the shank pieces invariably positioned on the shoe with thesurfaces of the shank pieces appropriately related to the surface of theinsole and with the shank pieces uniformly located on the shoe so as tofacilitate the application of the outsole.

To this end, an important feature of the invention consists in thecombination with mechanism for operating on a shoe having a shank pieceloosely superposed thereon, of

:: means mounted on the frame which carries said me hanism forpositioning the shank piece relatively to said mechanism. Preferably,and as shown, the member which engages the shank piece is formed withsurfaces angularly related to each other in such a manner as to engagethe shank piece at each side of the break line of the shank piece.-

t has been determined by experiment that as regards shoes of the samesize and like styles, the distance from the back of the shoe to thebreak' line of the insole is substantially constant. It results,therefore, that, if shoes of like size and like styles'are presented tothe fastening inserting machine with the backs of the shoes lo"ated at acertain predetermined distance from the shank piece positioning means,the shank plece, the location of which is determined 1 by the shankpiece positioning means, will invariably be accurately placed on theshoe. Accordingly, another feature of the invention resides inthe'combination with means for positioning a shank piece looselysuperposed on a shoe, of means for positioning a shoe so that the shankpiece will be propfirly located on the shoe,

In order that the invention may be con- Veniently employed in themanufacture of shoes of different sizes and styles the shoe positioningmeans, in accordance with a still further feature of my invention, ismade readily adjustable relatively to the shank piece positioning means,and means are pro vided for indicating the proper position of the shoepositioning means for operation upon a shoe of any size and style.

. The invention also contemplates the arranging of the shoe positioningmember in such manner as to enable the operator to present the shoe inproper position with relation to the shank piece positioning means andthe fastening inserting mechanism with the greatest possible ease andquickness. Accordingly, the shoe positioning member is mounted formovement in a vertical plane and is normally positioned below the planeof the fastening inserting mechanism in full View of the operator and insuch location that the operator can engage the shoe therewith withoutobstruction. After engagement of the shoe with the shoe positioningmember, said member is moved upwardly by the shoe in the presentation ofthe work to the fastening inserting mechanism. Preferably and as shown,for the purpose of ex- Jediting the presentation of the work to theastening inserting mechanism, means is provided for maintaining the shoeengaging surface of the shoe positioning means in substantially the samehorizontal plane in different adjusted positions of the shoe pcsitioningmeans.

The invention also contemplates the mounting of devices on the frame ofthe fastening inserting machine constructed and arranged to position theshank piece at its rear end and to support the shank piece independentlyof the shoe in a position determined by the shank piece positioningmeans. I

It is recognized that the invention-is not limited to the particularembodiment thereof herein described and illustrated or to operation onshank pieces of the special form described; for example, certainfeatures of the invention are applicable to the attachment of relativelylight shank pieces such as are used in the cheaper grades of shoes andwhich do not have a. defined break line. It is intended therefore thatthe scope of the invention shall be limited only by the language of theappended claims.

Other objects and features of the inven tion will appear as thedescription proceeds.

The invention. will be described, by way of example, as applied to afastening inserting machine of the type disclosed in United. tjtatesLetters Patent No. 1,106,393, granted August 11, 191 on an applicationof Fred lli. Mackenzie, and reference may be made to said Letters Patentfor a complete description of parts not fully described herein. Themachine comprises a nozzle or throat-piece 2 through which fastening-Spass for insertion into the work, the fasten'. being; forced. into thework by a driver 4i which reciprocatcd upwardly and down Wardly insuitabie guides in the machine frame 6. The illustrated machine is ofthe class which inserts previously formed fastenings of relatively smallsize hereinafter sometimes denominatec tacks, and the operation of themachine is controlled by treadle, not shown, which is operativelyconnected by a rod 8 to a starting and stopping mechanism denoted by thereference numeral 10, Fig. 1.. The above described parts constitute inthemselves no part of the present invention and are fuliy set forth inthe Letters Patent above referred to, for which reason a fullerdescription thereof is deemed unnecessary. Although the invention isdescribed in its application to a machine for attaching; shank pieces toshoes by metallic fastenings, it is to be understood that the inventionin its broader aspects is not limited to any particular form. of shankpiece attaching means.

lin the use of the machine a shank piece 19. is secured to the insole ofa shoe it by means of tacks 16 and 18, his. t, driven through the shankpiece nearits rear end and at either side of the metal strip 20 whichserves to reinforce the shank piece.

As above stated, it is desirable that the shank pieces be properly anduniformly positioned relativelyto the soles of the shoes and to thepoint of insertionof the fastenings. To this end, I have mounted on theframe 6 of the fastening inserting machine a shank positioning member 22adjustably secured to the frame of the machine by bolts 24 passing,through slots 26 in the up per end of the shank positioning member..r-tdgustably secured to the shank pOSl'tlOlllDg F member ,dtat ts lowerend, means of a bolt or the like28, is a gage member 30 which is formedwith shank engaging surfaces 32 and 341- angularly related to eachother, the shank engaging surface 852 being arranged to engage the planesurface 36 at the end of the shank piece forwardly the break line to ofthe shank piece and the shank engap} ing surface 3d being designed forengagement with. the curved upper su face 88 of the body of the shankpiece 12 adjacent to and rearwardiy of the break line 40 of the shankpiece. When a shoe with a shank piecesupergoscd thereon is presented inoperative relation to the throat piece of the fastening insertingmachine, the shank engaging surfaces of the shank positioning; member 22will engage the shank piece and position the same relatively to theinsole of the shoe and the throat 9. of the fastening insertingmechanism.

As hereinabove stated, it has been found by experiment that shoes of thesame size and of the same or like styics do not differ appreciably intheir dimensions from the backs of the shoes to the break line betweenthe shank and forepars of the insole. lit foilows, therefore, that ifmeans are provided for positionin the backs of the shoes always in thesame relation to the shank positioning means when OPGIEttT'lQ; on shoesof like size, the shank pieces will be located on the shoes with greataccuracy and uniformity. lin the illustrated embodiment of theinvention, the shoe positioning means comprises a work engaging member4:2 carried by the frame 6 of the machine. Since the distance betweenthe back of the shoe and the breals: line between. the shank and theforcpart varies in shoes of different sizes, means are provided foradjusting the work engaging member 4.9. for different sizes of shoes,and means are also provided for indicating the proper position ofadjustment of the work engaging membe for shoes of any size. ids-idmeans comprises bracket at in which is journaled a rock shaft 46carrying an arm d8 upon which the work engaging member is fuicinmcd, asindi cated at 50, it will be ciear from the foregoing); that if theshaft as is rocked or oscillated in either direction, the position ofthe wor; eiipgag" surfaces of the work onmember rciatiyr-ily to throatpiece 2 of the fasteninn i sorting mechanism and the shank positioningmeans will be changed. Means provided for footing; oscillating movementof the rock shaft 46 in the form of an arm 52 fixedly mounted on the endof the rock shaft 41:6 and extending upwardly therefrom to a pointadjacent to the indicator scale 54, which is toothed or serrated at 56for engagement therewith of a spring; pressed trigger 58 carried by thearm 52, the serrations 56 and trigger as operating; to maintain the arm52 and perforce the rock shaft 46 and work engaging member 42 in anyposition of adjustment to which they may be moved. As plainly appearsfrom Fig. 2 of the drawings, the indicator scale 54 marks the properpositions of adjustment of the work engaging member 42 for the dlfferentsizes of shoes. 7

It is important that in all positions of adjustment of the work engagingmember 42 relatively to the throat piece 2, the work engaging surfacesshould lie normally in substantially the same horizontal plane, to theend that the operator may not be inconvenienced by the necessity ofobserving the position of the member 42 each time work is presented tothe machine but may present the work in operative relation to the workengaging member without conscious inspection of said member which he cando by familiarizing himself with the location of the work engagingmember, if the normal work receiving position of the member is notmaterially changed when adjustments are made. In the present instance ofthe invention, this is effected by the provision of a spring 60, Fig. 1,which operates against the pin 62 carried by the work engaging member 42in a dlrection to urge the work engaging end of the member downwardly,and a cam member 64 extending rearwardly from the bracket 44 in positionto be engaged by the pin 62 to limit the downward movement of the workengaging member 42. By reference to Fig. 1, it will be seen that byreason of'the pivot 50 of the work engaging member 42, being arrangedsubstantially in the vertical plane of the rock shaft 46, a movement ofthe arm 52 in either direction from the position illustrated in saidfigure will tend to move the work engaging member 42 upwardly. It willbe further noted, however, that in the positioin of the parts indicatedin Fig. 1 the pin 62 is substantially in line withthe lowest point ofthe cam' 64. Since the curvature of the cam member 64 from its lowestpoint in either direction is greater than the curvature of the path ofmovement of the pivot 50 about the rock shaft 46, when thework engagingmember I 42 is moved in either direction from the position shown in Fig.1, the tendency'of the work engaging end of said member to be raised bythe bodily movement of said mem ber is countervailed by angular'movement of said member 42 on its pivot 50 due to the pin 62 havingimparted thereto an upward movement of greater extent than that of the1)1V0t 50.

The bracket 44 is carried by a member 66 shdably mounted in ways 68extended from the machine frame 6. Means are preferably provlded foradjusting the slide 66and the parts carried thereby in the ways 68 and,as

illustrated, such means comprises rack teeth to the throat-piece oftoning may be inserted 70 formed on the slide (36 and engaged with theteeth of a pinion stud 72 journalcd in ways 68. The slide G6 may belocked in any position of adjustment in the ways 68 by the bolt 74, Fig.1.

It has been found in practice that the distance between the back of ashoe and the break line between the shank and the forepart of the insolealthough the same in shoes of like sizes and of like styles. may differin shoes of different styles though of the same size. t follows,therefore, that if the parts are so related that the indicator 54 whichmay be called the size indicator properly signifies the position of thework engaging member when operating on shoes of a certain style, suchsize indicator might not mark the proper position of adjustment of saidmember for shoes of different style.

By movement of the work engaging mem ber 42, the bracket 44, and thesize indicator 54 together in the appr priate direction relatively tothe shank positioning means 22 to an extent equal to the amount by whichthe distance between the back ofthe shoe and the break line in shoes ofthe style to be operated upon differs from the distance between thecorresponding parts of a shoe of like size of the style for which theparts are set, the size indicator may be made to denote correctly thepositions of adjustment of the work engaging member for shoes of thestyle to be operated upon. Such move ment is effected by sliding thebracket 44 in the ways 68, and in order that adjustments for changes instyles may be accurately made the pinion stud 72 carries a finger 76associated with an indicator 78 which may be termed the style indicator.

In the use of the mechanism hcreinbcfore described, a shank piece whichmay be of the form shown in Figs. 4. 5 and G is applied to the shankportion of the insole of a shoe as portrayed in Fi 4, and the shoe withthe shank piece superposed thereon is presented the fastening insertingmachine in position such that a fastening may be inserted through therear end of the shank piece at one side of the metal strip of the shankpiece as indicated at 16, Fig. 4. The shoe and the shank piece are thenmoved together laterally and again presented to the throat-piece of thefastening inserting machine in a position such that a second iii-is asindicated at 18, the shank piece ataccording to the usual factorypractice, placed on a rack or other device whereby the shoe may betransported to the machine for laying the outsolcs thereon.

The shank piece may be presented in proper relation to the throat pieceof the fastening inserting machine previous to and independently of thepresentation of the 4. The shoe with tached thereto is then retreat and6) and are constructed to yield upon the insertion of the metal strip oftheshank piece between them and to engage the strip frictionally in amanner such as to permit 522 being omitted. It is preferred, however,

ready lateral movement of the shank piece from one tack insertingposition to the other but strongly enough to sustain the shank pieceadjacent to or in contact with the throat piece of the fasteninginserting machine and in engagement also with the shank piecepositioning means 22. It will be understood that the shank piecesupporting device S t also operates as a gage to position the shankpiece at its rear end and that said device might be relied upon, ifdesired, as the sole positioning means for. the shank piece, the shankpiece positioning member to utilize the member 22 to position the shankpiece longitudinally of the shoe and to depend upon the device 84 tosupport the shank piece and to position the rear end of the shank piecelaterally. The shank piece having been placed in position, the shoe ispresented to the fastening inserting machine,

being accurately positioned by thework engaging member 4-2. In theoperation of the outsole molding machine the sole is positionedrelatlvely to the device which molds the sole and forms the break linein the sole called the size indicator." When it is intended to moldsoles for shoes of acertain size the gage is moved until the pointer ofthe indicator which-is connected with the gageregisters with thecorresponding member on the indicator scale. l romthe foregoing, it willbe clear thatsolesintended for shoes of the same size will be of uniformdimensions from the heel seat end of the sole to the break line.Adjustments for various sizes are made by moving the gage toward andfrom the mold thus commensurately decreasing or increasing-the distancebetween the heel seat endof the sole and the break Shoes of like sizebut of unlike styles line. sometimes require soles of. difi'erentlengths. A second indicator Wl'llClT may be denomn hated the styleindicator is therefore provided to'markthe extent of adjustment of thegage member and the size indicator necessary to cause the latter toindicate accurately the positionwof the gage appropriate to a soledesigned for a shoe of a different style from that for which the moldingmachine has previously been set.

It will be clear from the above that adjustments of applicantspositioning member 42 may be made in accordance with the adjustments ofthe outsole molding machine, applicants size indicator and styleindicator being set correspondingly to the size indicator and styleindicator of the molding machine. Thedistance between the back of theshoe and the break line of the shank piece may thereby be made to bear adetermined constant relation t the distance be tween the rear end of theoutsole and the break line ofthe outsole. The outsoles are made of alength to extend somewhat beyond the backs of the shoes when appliedthereto, and since, by the use of the mechanism hereinbefore describedinasmuch as the shank pieces are uniformly located the amount of suchprojection is made constant when the outsole is properly applied to theshoewith the break line ofthe outsole coinciding with the break line ofthe shank piece, the operator is enabled to locate'the outsoleon theshoeaccurately and conveniently by holding the outsole right side up in onehand and with the other holding the shoein upright position and applyingit to the outsole with the back of the shoe spaced by the known distancefrom the end of the outsole. This method of operation possesses verymarked advantage over present methods, which involve much moremanipulation of the work and in which one of the elements, a. a, thebreak line of the shank piece, which are relied upon to locate theoutsole is rendered invisible in the operation of laying on the outsole.The tendency in laying on outsoles according to the present method isfor the operator to feel with the outsole for the break line of theshank piece inorder to determine the correct position of theoutsole. Thecement applied to the parts prevents, however, movement of the outsoleon theshoe and thus precludes the positioning of the shank piece in theabove manner.
